The ThermoLogRR RTD thermometer enables a user to log up to 1000 temperature readings, in real time, ranging from -330 to 2210F (-200 to 1210C) with an accuracy of I0.06F (I0.03C). It simultaneously monitors current, minimum, and maximum readings. Once in memory, the temperature readings can be recalled and displayed on the easy-to-read LCD, transferred to an available infrared printer or to a PC via an RS-232 interface onboard. The unit weighs 1 lb (0.5 kg), including batteries, measures about 3 in. wide x 1 in. long x 6 in. high (80 x 25 x 150 mm), and features a sturdy molded plastic case with sealed silicone membrane keypad. The unit is field selectable for Fahrenheit or Centigrade readings and carries a IP54 rating, dust sealed and suitable for use in water spray from all directions.
